Abstract: 1,265,588. Automatic exchange systems. SIEMENS A.G. 20 March, 1970 [21 March, 1969], No. 13456/70. Heading H4K. A programme controlled data processing system has a programme control PW with a command register BS output from which is registered in operations and address section stores OT, AT, with associated output decoders OD, AD, a processing unit IW having at least one-operand register, such as OR1, the bit length of the address section store AT being at least-equal to the bit length of the operand register, the address section AT being used to transfer data from the command register BS to the processor by way of a path l1. As shown in Fig. 2, the path l1 has one limb giving access to operand registers OR1, OR2, from bus B2, and has a second limb providing access to processing units such as comparator C, AND and OR-circuits U and O, and a one-adder 1A. From the operand registers the data may be sent by way of intermediate storage registers to external devices as when signalling the fact that a wanted path in a telephone switching network is blocked. The data sent from AT over path l1 may be masking data to indicate which portion of an operand register word is -to be taken into account as may be required in determining the sequence of available path sections in a switching stage. A processing sequence can be made repetitive by lodging an instruction in operand register OR2, or by instruction of the processing units, or by the presence of a repeat function in address section register AT. Interaction between intermediate registers and an operand register may be employed to collect dialled digits, the incoming data groups being of a bit length that can be coped with by the operand register. Jump commands to effect a programme sub-routine are requested over a path l3 either on direct application from the processor units or by way of a decision made in jump switching network SN. Operand registers may obtain access to data in specific locations by delivery of addresses direct to decoder AD over path 12.

Abstract: 1297507 Cardiac pacemaker VITATRON MEDICAL NV 3 Feb 1970 [3 Feb 1969] 5195/70 Heading A5R [Also in Division H3] A cardiac pacemaker adapted to be coupled to, and controlled by the R-peaksignal of the human heart comprises a multivibrator, comprising transistors T9, T7 cooperating with resistors R17, R19-R22 and capacitor C12, an input amplifier of bandwidth 20-50 hz, comprising T1, T2 cooperating with R1-R6 and C1-C4, a further transistor T5 which serves as a member conducting signals the voltages of which are over a certain threshold voltage, switching transistors T4, T6, T8 an auxiliary amplifier including a transistor T3, cooperating with C5-C6, R7-R9, and an output amplifier comprising T10, cooperating with C13, C14, R23-R25. Power is derived from a battery connected between conductors Al and A2. An electrode, not shown, connected with a ventrical of the heart, is connected to the input amplifier via conductors A3, A5 and the amplified R-signal passes through C7 and R10 to the base of T5, the collector of which transistor is connected to a pole of the battery of lower potential than that connected to A2. When the amplified R-signal reaches the threshold voltage of T5, T6 is adapted to be rendered conductive and an impulse is supplied to the base of transistor T9 of the multivibrator causing a drop in the potential of the base of T9 which transistor is thus rendered conductive, a voltage pulse is developed across R21, amplified through T10 and delivered to the conductor A3 and thence to the heart of a patient. If a QRS complex occurs, the amplified R-peak-signal will cause transistor T8 to conduct and short-circuit R21. Owing to the action of a delaying circuit comprising R14 and C10, T9 will receive the signal at a time later than T8 and thus when a QRS complex occurs, the impulse from the multivibrator is prevented from reacting T10. R15 and R17 act as a potential divider preventing T19 from becoming conductive until C12 is at least partially discharged through R20. When an impulse from the multivibrator is supplied to A3 voltage is developed across R24 which voltage is fed across the base and emitter of T4, which transistor is adapted to be rendered conductive on receipt of such a voltage thereby connecting the base of T5 to the conductor A2 and rendering T5 non- conducting, thus preventing an influence of this impulse back on the multivibrator. If an interference signal, e.g. a series of repetitive pulses, is received, C6 which is in the input circuit of the auxiliary amplifier constituted by T3, which transistor is in parallel with the threshold transistor T5, is charged at each pulse and the potential increases to such a level to render T4 conductive thus shorting transistor T5 and preventing the signal reaching the multivibrator. At the termination of the interference, C6 discharges and the normal situation is restored. R10 is adapted to isolate T4 from T3. The natural frequency of the multivibrator may be checked by closing the reed relay P1 by means of a magnet thus short-circuiting the input amplifier.

Abstract: 1309751 Transmission mechanism for vehicles BRITISH & FOREIGN TOBACCO CO Ltd 12 March 1970 [13 March 1969] 13344/69 Heading B7E [Also in Division F2] In a transmission mechanism for converting reciprocal motion into rotating motion, especially for bicycles, downward movement of the pedal 4 is transmitted via crank lever 4a to the curved lever 6, these components being rigidly connected together and pivoted about a stationary pivot 5, thus causing upward displacement of the coupling lever 7 which engages with the scalloped edge of lever 6 through the pin 8, so that the drive lever 10, joined to the lever 7 by the pivot 11, is pivoted clockwise about the axle 12, which is fixed, e.g. to the frame of the bicycle, and transmits motion to the sprocket drive wheel 14 via the sprocket chain 13, one end of which is joined to the upper end of lever 10 and the other end to a point on the circumference of wheel 14, causing anticlockwise rotation of the axle 15 and the large sprocket wheel 16 which is keyed to axle 15. Drive wheel 14 is joined to axle 15 by a free wheel mechanism, and when pressure is removed from pedal 4 drive wheel 14 is rotated clockwise to its original position by the action of a restoring spring (not shown), thus restoring pedal 4 and levers 4a, 6, 7, and 10 to their original positions. The anticlockwise motion of the sprocket wheel 16 is transmitted via the chain 17 to the sprocket wheel 18 which is keyed to the shaft of the rear wheel 3. The mechanical advantage of the system may be changed by pivoting the lever 7, and thus the pin 8, relative to the scalloped edge of the lever 6. This may be achieved automatically by a mechanism such as the speed governor in Fig. 3 (not shown), which is situated at the centre of rear wheel 3, and causes displacement of the lever 9, thus pivoting lever 7. Alternatively there may be an arrangement for displacing lever 7 manually.

As described, a mandrel is extruded in continuous lengths from a solder extrusion press, lubricated and wound on to a reel. The mandrel comprises non heat-degradable, thermoplastic material such as lead/tellurium/antimony or lead/bismuth/tin. Rubber tubing is extruded in a continuous length on to the mandrel from the reel, tested for spark breakdown and then frozen. Textile is braided on to the tube and the hose and mandrel wound on to reels. The hose and mandrel pass through a rubber extruder for an outer rubber sheath, and a catenary curve vulcanizing steam pipe, thereafter passing a corona and concentricity test and being branded and cut into lengths. The mandrel lengths are extracted from the cut hose by (i) hydraulic pressure, (ii) dielectrically heating the mandrel and blowing the liquid lead alloy from the hose, or (iii) inserting the hose and mandrel into a pipe, forcing in a piston to bunch the hose against a lip and eject the end of the mandrel, and pulling the mandrel out with pliers. The extracted mandrel lengths are melted and recycled. The hose lengths are mechanically inspected.
